Millennials are often maligned for their shopping habits, but not yet for selling Grandma’s wedding ring to pay the rent.

Provident Loan Society of New York — a nonprofit that provides microloans secured by valuable jewelry — reports that the number of new customers applying for loans is up 8 percent year-to-date compared with 2015. Most clients are under 35 years old.

“These are people who have inherited jewelry and might have a shortfall on their rent or a medical bill,” Scott Watson, chief marketing officer, told our Lisa Fickenscher. Upper East Side-based Provident was founded by J.P. Morgan and Cornelius Vanderbilt in 1893.

Provident is holding an auction on July 12 at Doyle New York of baubles belonging to borrowers who either couldn’t pay off their loan or chose not to.

Among the items is an 18-karat gold Bulgari bracelet with 24 diamonds for an estimated $5,000.
